[R] Assign Formulas to Arrays or Matrices?

[McLovin]

Hi,

I am very new to R.  I am hoping to create formulas and assign them to
locations within an array (or matrix, if it will work).

Here's a simplified example of what I'm trying to do:

form.arr <- array(31,5,3)
for (i in seq(from=1, to=31, by=1)) {
	for (j in seq(from=1, to=5, by=1)) {
		form.arr[i,j,] <- as.formula(y~1+2)
	}
}

which results in this error:
Error in form.arr[i, j, ] <- as.formula(y ~ 1 + 2) : 
  incorrect number of subscripts

The reason I had made the 3rd dimension of the array size 3 is because
that's the length R tells me that formula is.

When I had tried to do this using a matrix, using this code:

form.mat <- matrix(31,5,3)
for (i in seq(from=1, to=31, by=1)) {
	for (j in seq(from=1, to=5, by=1)) {
		form.mat[i,j] = as.formula(y~1+2)
	}
}

I was told:

Error in form.mat[i, j] = as.formula(y ~ 1 + 2) : 
  number of items to replace is not a multiple of replacement length

My question is: is it possible to assign formulas within a matrix or array? 
If so, how?  Thanks.not at real.com
